The former Wham! star was airlifted to hospital with cuts and bruises after the accident on the M1 motorway north of London on Thursday

Police have launched a probe into the incident and details of how George came to be injured have not been revealed, but now an eye-witness has come forward to suggest the Michael fell from an open door of the vehicle as it travelled at high speed.

Motorist Katherine Fox was driving along the same stretch of highway when she saw the bloodied and shocked star sprawled in the road.

She tells The Sun newspaper, “There was a nasty cut on his forehead and the back of his head. There was blood all down his face and on his teeth. He was breathing and conscious but in shock. … I asked what had gone on and was told he tried to open the car door and shut it again because it wasn’t shut properly and apparently fell out at 70 mph.

“I was on the phone to the ambulance and said, ‘You’d better come quick. This doesn’t look good’. George was wearing a black and gold Adidas tracksuit that was ripped all down the arm and shoulder. He had no trainers on. … His sunglasses were also in the road. … I think George was lucky he didn’t die.”
